Application of Lalium germplasm in breeding of available Lalium species requires sufficient information about different aspects, including variIous karyotypic characteristics. For this reason, nine populations of Lalium multiflarum and L. rigidum species, randomly taken from Natural Resources Gene Bank, were investigated for karyotypic characteristics. Five metaphase cells were studied from each population for several karyotypic characteristics, including long and short arm length, by which total length of the chromosomes, long arm to short arm and short arm to long arm ratios were calculated. The number and locations of the possible satellites were also identified. Using several available estimation formula, karyotypic asymmetry of the populations were also investigated. Using Levan ratios, karyotypic formula of the populations and species were also determined. Amongst the studied populations, two populations were tetraploid, five populations were diploid and two populations were a mixture of tetraploid and diploid genotypes. Several populations had one to two satellites on their chromosomes. Most of the observed chromosomes of the populations were metacentric, in which the centromers were located in median region. Based on one of the karyotypic asymmetry measurment parameters, DRL, within the tetraploid populations, two populations of L. multiflorum showed the most symmetric and asymmetric karyotypes. Within the diploid populations, a population of L. rigidum species showed the most symmetric and a population of the L. multiflorum species showed the most asymmetric karyotype.

Effects of five NaCl dosage treatments, 0, 50, 100,150, and 200 mM were carried out on germination of two rangeland species including Melilotus officinalis and M.alba. Germinatin percentage, radicle and plumule length were recorded and the data were analyzed by one-way ANOVA. The salinity showed a significant effect on germination percentage and radicle length but not on plumule length. Also, polynomial analysis of results showed a significant effect with a linear trend. In Malba salinity effects on all traits were statistically significant. Polynomial analysis on germination had a linear trend, whereas, radicle and plumule length had squared trend. Bivariate correlations coefficient in M. officinalis, between radicle and plumule length and between radical and germination percentage were statistically significant. In M.alba, correlation coefficient between radicle length and germination percentage was significant.

In pistachio, the majority of fruits does not reach maturity and drop up to 8 weeks after pollination. The fruits that reach maturity, a proportion are abnormal, seedless (blank) or their shell is not split. In this study, pollination and fruit development were investigated in relation to abscission and abnormalities. A medium containing 1% agar and 10% sucrose was used to assess the pollen quality. Fresh and 24 hours dried pollen showed high germination in vitro as did pollen stored at freezer (-15°C) up to usage time. The stigma surface of Pistcia vera turned to pale red with some secretion on top and among papillas at anthesis. Female Pistacia vera trees were hand pollinated with pollen from male of P. atlantica and P. vera at 0, 1, 2, 3, and 4 days after anthesis. Results were measured by mature fruit set and by fluoresence microscopy of pollen germination and tube growth in the pistil. Maximum pollen tube growth and fruit set of split nuts were achieved following pollination within two days of anthesis. Three days old pistils supported pollen tube growth, but fruit set was low. Four days old pistils supported little pollen tube growth and fruit set. Significant differences were also apparent between pollen parent, with low pollen tube growth and fruit set following inter-specific pollination with P. atlantica pollen. All pollen tubes were observed to penetrate chalazogamously, and parthenocarpic production of blank fruits occurred in both unpollinated and pollinated treatments. The results indicated that for optimum fruit production of pistachio, pollen transfer must be achieved within two days of anthesis and inter-specific pollinator genotypes should be abandoned.
